Observation of the reversed Cherenkov radiation [PDF]
Nature Communications, 2017 Reversed Cherenkov radiation has not been observed due to the absence of suitable all-metal left-handed materials for beam transport and suitable couplers for extracting the signal. Here, Duanet al.

Slow Group Velocity and Cherenkov Radiation [PDF]
Physical Review Letters, 2001 We theoretically study the effect of ultraslow group velocities on the emission of Vavilov-Cherenkov radiation in a coherently driven medium. We show that in this case the aperture of the group cone on which the intensity of the radiation peaks is much ...

Cherenkov radiation in a gravitational-wave background [PDF]
Classical and Quantum Gravity, 2001 A covariant criterion for the Cherenkov radiation emission in the field of a non-linear gravitational wave is considered in the framework of exact integrable models of particle dynamics and electromagnetic wave propagation.

On-chip Cherenkov radiation tuning in 3.2-14 THz [PDF]
Nature CommunicationsCherenkov radiation has attracted much attention for promoting the free electron radiation sources. Using hyperbolic metamaterial, Cherenkov radiation can be excited using low-energy electrons and thus on-chip free electron radiation source has been ...

Dispersive 2D Cherenkov radiation on a dielectric nano-film [PDF]
Scientific Reports, 2017 We report a modified two-dimensional Cherenkov radiation, which occurs on a high-index dielectric nano-film driven by uniformly moving electron-beam. It is essentially different from the ordinary Cherenkov radiation in that, in the nondispersive medium ...

Backward Cherenkov radiation emitted by polariton solitons in a microcavity wire [PDF]
Nature Communications, 2017 Cherenkov radiation is generated from fast electrons and its optical analogue plays an important role in many nonlinear optical effects. Here, Skryabin et al.

On Tamm's problem in the Vavilov-Cherenkov radiation theory [PDF]
, 1999 We analyse the well-known Tamm problem treating the charge motion on a finite space interval with the velocity exceeding light velocity in medium. By comparing Tamm's formulae with the exact ones we prove that former do not properly describe Cherenkov ...

Cherenkov Radiation Control via Self-accelerating Wave-packets [PDF]
Scientific Reports, 2017 Cherenkov radiation is a ubiquitous phenomenon in nature. It describes electromagnetic radiation from a charged particle moving in a medium with a uniform velocity larger than the phase velocity of light in the same medium.

Cherenkov Gravitational Radiation during the Radiation Era [PDF]
Universe, 2021 Cherenkov radiation may occur whenever the source is moving faster than the waves it generates. In a radiation dominated universe, with equation-of-state w=1/3, we have recently shown that the Bardeen scalar-metric perturbations contribute to the ...
